S1 a=c

S2 b - a < c
Statement 1:
a = c,
If b > a and c
then set = {c,c,b}
If b < a and c
then set = {b,c,c}
If b = a and c
then set = {c,c,c}

In all the cases, "c" is the median. --- Sufficient

Statement 2:
b - a < c
b = 2, a = 1, c = 1.5 -- Yes (1,1.5,2)
b = 1, a = 1, c = 2 --- No (1,1,2) --- Not Sufficient

Hence, A
Thanks

hmhm thanks
i was dumb. i think of the case when b=a=c and i thought what if they are all the same? then can c is median and i answered no... lol
